臺北市緊急車輛優先號誌之應用與管理

Application and Management of Emergency Vehicle Preemption Signals in Taipei City

臺北市交通管制工程處執行「112-114年臺北市導入智慧動態號誌控制策略計畫」，號誌路口啟動緊急車輛優先號誌功能，整合消防局「高效能勤務派遣系統」每1秒傳送救災救護車輛之GPS定位座標及案件資訊，即時掌握車輛出勤狀況及行駛路徑等資訊，一旦緊急車輛進入號誌路口觸動範圍，系統立即演算開啟下游路口號誌綠燈，提升緊急車輛通行效率及安全，本計畫於2024年5月完成系統佈署與線上實測，執行範圍涵蓋台北市東西向民族西路、民權西路、民生西路及南京西路及南北向之中山北路、承德路、重慶北路、環河北路等八條主要幹道交織而成的67處路口，統計事前(2024年4月1日至5月12日) 1,479筆和事後(2024年8月19日到9月15日) 1,348筆車輛派遣案件，緊急車輛在計畫執行範圍內各路徑旅行時間改善幅度介於4.0%~26.8%，整體運作績效改善幅度為9.3%，在系統控制下，緊急車輛可於綠燈時相通過路口的比率可達83.62%。

The Taipei City Traffic Engineering Office (TTEO) is executing the ''2023-2025 Taipei City Intelligent Dynamic Signal Control Strategy Implementation Project. ''As part of this initiative, the Emergency Vehicle Preemption (EVP) function has been activated at signalized intersections. This system integrates with the Fire Department’s ''High-Efficiency Dispatch System,'' which transmits the GPS coordinates and incident information of fire and ambulance vehicles every second. This enables the system to instantly monitor vehicle deployment status and travel routes. Once an emergency vehicle enters an intersection's activation zone, the system immediately calculates and opens the green light for the approaching vehicle at downstream intersections, significantly enhancing the efficiency and safety of emergency vehicle transit system deployment. On-site testing for this project was completed in May 2024. The implementation scope covers 67 intersections formed by the convergence of eight major arterial roads in Taipei City (East-West: Minzu W. Rd., Minquan W. Rd., Mingsheng W. Rd., Nanjing W. Rd.; North-South: Zhongshan N. Rd., Chengde Rd., Chongqing N. Rd., Huandong N. Rd.). Compared 1,479 vehicle dispatch cases from the pre-implementation period (April 1 to May 12, 2024) with 1,348 cases from the post-implementation period (August 19 to September 15, 2024)., The results are as follows: The travel time improvement for emergency vehicles within the project scope ranged from 4.0% to 26.8% across various routes. The overall operational performance showed an improvement of 9.3%. The success rate of emergency vehicles passing through intersections during the green phase reached 83.62%.
